Lumber Dimensions. 2x4s are not actually 2 inches by 4 inches. When the board is first rough sawn from the log, it is a true 2x4, but the drying process and planing of the board reduce it to the finished 1.5x3.5 size. Here are the common sizes of lumber, and their actual sizes.
A 2X6 is 5 1/2 inches wide. Incidentally it's 1 1/2 inches thick. Pre-WWII lumber was cut at stated dimensions, a 2x4 was actually 2 inches by 4 inches. 2X6 (dry Douglas fir) weighs 2lbs per foot. Thus a 20ft 2X6 would weigh 40 lbs. Other types of lumber such as pine weighs more and all lumber is heaver when wet or if it has â¦ been treated.
